Aim:
The study analyses the short- and long-term clinical results in 112 patients with total or partial edentulia of the jaw undergoing oral implantology in order to assess the type of surgical complications.
Methods:
A total of 327 implants were inserted with an internal hexagonal screw, a diameter of between 3.25 and 5.5 mm and between 11 and 15 mm long. Each patient received three types of implant: overdentures, bridges supported by implants alone and bridges supported by implants and natural teeth.
Results:
In line with other data reported in the literature, the failure rate at 7 years was 3%.
Conclusions:
After a general discussion of the possible surgical complications arising during implantology, the authors describe and analyse all the surgical complications that occurred in this series, regarding both implants alone, bridges supported by implants and natural teeth.
